About The Study: In this study, confidence in organizations to use health data responsibly was largely unchanged from 2020 to 2022, but polarization increased between politically liberal and conservative respondents. Compared with 2020, in 2022 liberal respondents reported increased confidence in the federal government to use digital health data responsibly, while conservative respondents reported decreased confidence in the federal government and agencies. Changes in confidence may be related to the prominence of these agencies (CDC, NIH) during the COVID-19 pandemic, a 2020 national election with a change in the governing ...

For nearly a century, scientists have known that different parts of the human brain’s cortex control different body movements. This fundamental discovery dates to the 1930s, when neurosurgeons used electrical stimulation to map how different cortical regions correspond to different body parts. But can these regions be further broken down into even smaller functional components? Researchers have long suspected that cortical units for specific body movements are more complex than simple patches in the cortex. Studies have identified various types of neurons stacked in multiple layers across the neocortex, but without a clear picture of how these ...

Oral cancer remains a serious global health concern due to its high morbidity and mortality rates, primarily caused by late-stage diagnosis. The presence of oral potentially malignant disorders (OPMDs) provides an opportunity for early intervention, as these lesions precede the development of oral squamous cell carcinoma. However, the accurate detection and classification of OPMDs remain challenging due to their diverse clinical presentations. Conventional diagnostic methods, including visual examination and histopathological ...

To develop a practical fusion power system, scientists need to fully understand how the plasma fuel interacts with its surroundings. The plasma is superheated, which means some of the atoms involved can strike the wall of the fusion vessel and become embedded. To keep the system working efficiently, it’s important to know how much fuel might be trapped. “The less fuel is trapped in the wall, the less radioactive material builds up,” said Shota Abe, a staff research physicist at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL).  Abe is the lead researcher on a new study published in Nuclear ...

A century of fire suppression, combined with global warming and drought, has led to increasingly destructive wildfires in the Western United States. Forest managers use tools like prescribed burns, thinning, mastication, and piling and burning to reduce fuel – live and dead trees, needles and leaves, and downed branches – that can feed intense wildfires. These methods aim to lower fuel levels, reduce crown density, and protect fire-resistant trees, fostering healthier, more resilient forests. However, prescribed burning efforts haven’t kept up with the rapid buildup of surface fuel, creating a “fire deficit” – the gap between the amount of fuel that has ...
